Pixelation of video footage

Hi guys, so i captured dv footage from a 3ccd panasonic md10000 using pinnacle studio 11 plus. the footage after being edited was then burned to a dual layer dvd. The quality icon on pinnacle stated 100% quality. when played on a 72cm tv the footage is fine, but when played on a 46inch led the footage pixlates. even worse the standards menus on pinnacle pixelates more. What am i doing wrong?
